To all whom it may concern:

Be it known that I, EnNns'r O. CART- wnrerrr, a citizen of the UnitedStates, resioing at Springfield, in the county of Clark md State ofOhio, have invented a new and improved Portable Pumping Apparatus, ofwhich the following is a specification. 1

This invention relates to an apparatus aoapted to be used for elevatingand transporting liquids mixed with solids or sediment, the propertiesof which make it impracticable to handle them directly through the pump,which app? "atus, in its complete makeup includes a motor drivenvehicie, a iquid carrying tank mounted thereon and adapted to be dumped,a pump for taking liquid from the tank and returning it, under pressure,to the tank, means to operate the pump by power from the motor vehicleand an ejector through which the liquid taken by the pump from the tankmust pass from the pump back into the tank.

prime objects of this i vention are: To provide 'an improved efficientportaole pumping apparatus of the general character stated, in which theral eleents that constitute the complete mechanism are so designed andcooperatively-so combined whereby the construction of such type ofportable pumping ap aratus is of a simple and economical nature.

Second. To provide a new and novel construction of parts that are solocated, relatively to each other, that the complete mechan m orapparatus is encon ss d in a comp I lv small limit of sp ce upon themotor vehicle frame and the tank without the use of troublesome andunsightly overluuigiug and upwardly projected parts.

Third. To provide an improved means for suspen ing the circulation ofthe liquid throi the pump, from and to thetank, in order that the pumpmay be utilized, will, for either normal elevating or pressure purposesv. th the intake from outsidesou" than the tank, or for direct pr irepurpose with the intake from the tan r. lVith these and other objects inview of which will hereinafter 1 car, my presout invention embod s thefeatures of construction and combina ion of parts to be fully exp. ed inthe following description, spezilicall pointed out in the appended 7being claims and illustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of a motor vehicle with my improved pumpingapparatus applied thereto, the pump, the ejector and the-tank beingshown in their relative positions, when operating.

Fig. 2 is a view similar to Fig. 1, the parts shown in the relativeoperative position, when the tank is being dumped.

Fig. 3 is a horizontal section of a portion of the tank, andillustrates, in plan view, the discharge pipe to the rear of the tank,the pump intake at the front end of the tank, the overflow and thefilter connection hereinafter specifically referred to.

Fig. 4 is a side elevation, partly in section, of the ejector and thestop or gate valve that cooperates therewith.

Fig. 5 is a detail view of the nipple connection for the upper end ofthe ejector.

Fig. 6 is detail sectional elevation of the parts that constitute thedetachable oint in the pump intake piping and the connection providedfor the intake, when it is desired to use the pump for normal elevatingpurposes.

Figs. 7 and 8 detail views hereinafter soecifically referred to.

in carrying out my invention, I use a tank 1 of any suitableconstruction and which includes a tail gate 1 that is pivotally mountedon the side members 2-2 of the motor vehicle frame, the gate being heldclosed by clamps 53 3 designates a hoist, a hydraulic jack of well knownconstruction, and 4: denotes a pump also of a well known construction,which pump is located on the motor vehicle frame between the front endof the tank and the back of the drivers seat.

As a specific construction of the tank, the motor vehicle, the pump andthe hoisting jack, per se, constitute no part of my in vention, furtherdetail description thereof is deemed unnecessary.

5, 6, 7, S and 9 designate threaded flanges mounted around openings intwo sides of the tank, at the front end thereof, and 10 designates apipe that is threaded into the flange 5 and from which flange the saidpipe extends rearwardly within the tank to a point in close proximity tothe tail gate.

At the rear end, the pipe 10 is supported in aranchor bracket 11 securedto the inner threads into the flange 9 on the outside of the tank andthe said connection 12 receives one end of a section or" hose 13 that isnormally supported upon brackets 1414 along the outside of the tank on aline higher up on the tank than the flange 9.

At its free end, the hose 13 has a coupling 13 adapted to be attached toa hydrant or other water supply (not shown).

A strainer 15 and a stop 16 are serially connected to the flange 7 andthe said cock 16 is provided with a lever 17 that has a pull rod orcontrol 18 which extends upwardly and outside of the tank for beingconveniently manipulated by the driver while on the vehicle.

19 indicates a coupling pipe, one end of which threads into the flange 8and whose other end threads into an elbow 19, the dependent or lower endof which is threaded to receive a flanged tapered nipple 20, as is bestshown in Fig. 6, from which it will be noticed that in fitting theparts, the nipple 20 detachably seats against a gasket 21 that is heldto its place by a retaining ring 22, in a recess 22 in a speciallydesigned flanged T coupling 23, which is coupled up with the intake ofthe pump, see Fig. 3.

The recess 22, in the coupling 23, merges with an annularly beveled seatagainst which the gasket 21 is bent back, when the nipple 20 is seatedin the coupling, as indicated by dotted lines on Fig. 6.

The T coupling 23 has a threaded opening 24 in which is threaded anipple 25 that is dapted to receive the coupling of a suction hose (notshown).

Normally the nipple 25 is held closed by .hose cap 26, as shown. r

The flangefi on the front end ofthe tank receives one end of a pipe27'whose other end threads into a specially designed elbow (see l ig. 8)and in a recess formed in the. base of the said elbow, a gasket 29 isheld in place by retaining ring 30, as shown.

i Vhen the tank is at the normal or down position, shown in Fig. 1, theelbow 28 seats onto a tapered. nipple 21 that is adjustably insertedinto the upper end of the ejector 32, the details of which are bestshown in Fig. 4. V l r V in fitting the parts into operative connection,the nipple 31 is packed up to the necessary point of contact with thegasket 29 by means of packing rings 33 and it is held to its place by aset screw 34 that threads through the upper end of the ejector, see Fig.5. v

The ejector 32 contains two channels or passages 35 and 38, oneofwhich35 is a straight way passage that originates at the lower end ofthreaded opening 36 and terminates at its top end in the seat for thenipple 31.

37 designates a nipple that screws into the wall of the ejectorintersects the constrict,

ed orifice 40 and connects with a threaded sleeve 42 that is normallyheld closed by a cap 43.

44 designates a stop or gate valve and the said valve is slidablyadjustable in the 41 having the opening 41. 1

The plug valve 44 includes a threaded stem .44 which terminates in ahead for receiving a suitable key 45 for which provision is made on thecap 43' for the convenient holding of the key ready for use, as shown inFig. 4.

The threaded stem 44 engages an internally threaded passage 42 in thesleeve 42, it being apparent from Fig. 4 that by removing the cap 43convenient access is had to the key receiving end ofthe stem 44 forturning such stem to feed the plug 44 to the closed position, shown inthe said Fig. 4, whereby to cut off the passage 38 that communicates,through the chamber 39, with the pump or for drawing it backward intothe tubular neck 40 when a clearness is desired between the deliveryfrom the pump and the constricted orifice 40 that joins with the ejectorpassage 35.

An outlet opening 46 connects the chamber 39 with a terminal 47 that isadapted to receive the coupling of a hose (not shown). The terminal4? isclosed by a hose, cap

A pressure gage 49 is optionally mounted onrthe chamber 39, as shown inFigs. 1, 2 and 3. V

The laterally projected flanged portion of the ejector 32 bolts to aflange 50 on the delivery end 4 of the pump 4, and the flanged portionof the '5' coupling 23 bolts to the intake face 51 of the said pump, asis clearly shown in Fig. 1.

designate sertional cover plates which are held downon top of the tankby winged bolt clamps 53-53, see Figs. 1 and 2, as hereinafter furtherexplained.

Petore proceeding with the'detailed description of the operation of theapparatus neck 7 liereinbefore explained and as shown in the drawings, 3functions of the said apparatus should be here stated, namely;

First. For the evacuation of cesspools, sumps, basins or depressions orexcavations in. which the character of the contents is such that theyshould not pass through the pump without partial separation from thesolids contained in them;

Second. The pumping of liquids directly by means of the pump anddelivering them either to the tank for hauling, or a distant point bypiping;

Third. F or purposes of spraying liquids from the tank or deliveringthesame, under pressure, at a distant point.

Referring now to the operation of the apparatus, the first function ormethod of its use Jest explained as follows:

Hose 13 is removed from its holding brackets 14-14 and its free endconnected to a source of water pressure, and through it the tank issupplied with suflicient water to cover the strainer 15. The hose 13 isthen disconnected from the water supply and permitted to hang rem itsconnection (see arrow a; on Fig. 1) to act as an overflow channel forthe tank.

The stop cock 16 is now opened by means of the pull. control 18, actingthrough the lever 17 when the water Within the tank passes through thepiping 19 and the coupling 23, to the pump, which latter is thus primedfor operation.

Upon application of power to the pump, water is forced through theconstricted orifice 4) of the ejector 32, forming a ct which creates apartial vacuum in the straightway channel or passage 35, causes thewater to pass up througn the nipple 31, the elbow 2-8 and the pipeconnection :27, into the delivery pipe within the tank, from whence itis discharged at the rear end of the tank.

Now, if the nipple 87 be connected to any cesspool, sump, basin or otherdepression which collects sediment or accumulations that recuireperiodically to be removed, the liquid and contaminations will be drawnup see dotted lines and arrow 2 on Fig. 1) through the ejector passage35 and the pipe and leposited at the rear of the tank where the sedimentand solids precipitate fore.

The overflow hose 13 conveys to any outside point of waste, thepartially clarified li uid that collects within the tank beyond thelevel of the hose connection to the tank.

The operation just explained is continued until the tank is desirablyloaded wit. precipitations, after which the pump stopped, hoseconnection 13 restored upon the brackets 14, the stop cook 16 closed,the lift pipe from the cesspool is disconnected from the nipple 37,after which the apparatus is transported to a desired point for thedumping of its contents.

In order to facilitate the dumping operation and to minimize adjustmentthat mi ght be required upon restoring the, tank to its normal position,the detachable asketed J. o 1 1 Joints in the T coupling 20 and in tneeioow 28, hereinbefore referred to, have been provided so that, when thefront end of the tank is elevated for dumping, as indicated in Fig. 2,the joinings mentioned will scga rate at the gasket 21 in the T coupling2 and at the nipple 31 on the elbow '28 and when the tank is restored(swung down) to the normal position, the two joints mentioned willautomatically close.

In eztpiaining the second fnnctioi orally stated, operation of the partsis as follows:

Stop cock 16 and the hose cap 26 is removed and the place of the latterin the nipple is taken by any suitable hose connected with any desiredsource of s pply.

The cap 43 (see Fig. 4) is removed, the key 45 is used to return theplug valve 44 to the closed position for stopping off the jet orifice40.

Cap 43 is then restored to its place on the plug 42.

Hose cap 48 is removed from the terminal 47 and its place is taken byany su able hose connection wherewith, by starting the pump, the liquidpumped may be oeposited either in the tank or at any other desiredpoint.

By reversing the changes enumerated for this last stated function, it isobvious ii at the apparatus is restored for use accordii. to the firststated operation.

For the third stated function, or use, the stop cook 16 is open and thehose cap is in its place closing nipple 25, the plug valve 44 being ateither the open or closed positionopen if it be desired to agitate theliquid in the tank, closed if only pressure at terminal 47 is desiredandthrough any suitable connection with the terminal 47, upon applyingpower to the pump, liquio in the tank may be disposed at any desiredpoint.

In an apparatus of this character, it is desirable to provide the tankwith a cover to avoid splashing of the contents, when in transitcarrying liquids and also to avoid unsightly effects on both apparatusand surmovable in order that the tank may be loaded from the top foruse, at will, for carrying masses other than liquids and to have theremoved cover disposed upon the tank so as to be available at all timesto be quickly restored to their functional location on the tank.

It is also a further desirability, that to facilitate transportationupon travelways, likely to be much used by an apparatus 01 the characterstated, that the ejector and its necessary means of connection with theplaces to be evacuated, add to the machine the fewest number ofprojecting or overhanging parts beyond the normal limits of spacenecessary for the passage of the vehicle upon which the apparatus ismounted.

To satisfy the desirability for a cover for the tank, I have providedthe plates 52, before referred to, and these are detachably placedcrosswise of the top of the tank 1 and they are held to their positionby the clamp members 53.

The plates 52 are slotted centerway oi"? each end to clear studs ofclamping screws 53and to render said plates removable at will.

Crosswise of the motor vehicle frame is .mounted a supporting bar standthe said bar is provided at each end with an upwardly extending stud 54onto which are received the slotted edges of the cover plates 52, whenthe latter are taken from the top of the tank, the said bar 54-constituting a convenient means for carrying the cover plates at alltimes on the apparatus.

Clamp devices 55 are provided for curely holding the plates in positionwhen assembled on the cross bar 54, see 2.

To fulfil the desirability for compacting I have so designed the ejector32 and correlated it with the other elements of the apparatus that thedesired ends are attained.

l/Vhile I have shown and described the special construction of coverplates, etc, yet I desire it understood that in this application I makeno claim, per se, to the said with the accompanying drawings, iti'sbelieved the complete constructromthe manner to dump the contents, apump on the vehicle adjacent to the end of the tank which is adapted tobe raised and lowered, an e ector carried by said truck and relativelyfixed asto position, said ejector having its ejectingnozzle entrance incommunication with the outlet of the pump and having its suctionentrance adapted to be put into communication with the sump to becleaned out, a discharge pipe for delivering the material fromtheeject'or outlet intothe tank, said pipe and said ejector having aseparable-section joint adapted to effect a water tight connection, whenthe'tank is down and'to be automatically disconnected, when the vtank israised, a suction pipe carried by the tank and a separable-sectioncoupling between said suction pipe and the inlet of said pump, whichcoupling is also adapted to effect a fluid tight joint, when the tank isdown and to be automatically disconnected, when the tank is elevated.
